Apple releases iOS 5.1.1 with fixes for HDR photos, AirPlay video

Apple on Monday released iOS 5.1.1 for iPhone, iPad and iPod touch, packing a number of fixes for various bugs, including issues that affected AirPlay video playback.

Users can now download the full update through iTunes, or access the smaller delta update directly on their iOS device through the Settings application. The software update is labeled as "Build 9B206."

The update is available for the iPhone 4S, iPhone 4 and iPhone 3GS, third- and fourth-generation iPod touch, and all iPad models. The full list of changes in iOS 5.1.1, as noted by Apple, are:

Improves reliability of using HDR option for photos taken using the Lock Screen shortcut

Addresses bugs that could prevent the new iPad from switching between 2G and 3G networks

Fixes bugs that affected AirPlay video playback in some circumstances

Improved reliability for syncing Safari bookmarks and Reading List

Fixes an issue where 'Unable to purchase' alert could be displayed after successful purchase

The last update to iOS arrived in March, and added Japanese language support for Siri, as well as quick lock screen access to the iPhone's native Camera application. It also gave users the ability to delete pictures from the iCloud-based Photo Stream service.

Apple is expected to unveil the next major update to its iOS mobile operating system next month at its annual Worldwide Developers Conference. The event will run from June 11 through 15 at Moscone West in San Francisco, Calif.
